DIB-IGIBLE HEADLIGHT.

Specification of Letters Patent.

Patented Sept. 4, 1917.

Application filed February28, 1917. Serial No. 151,518.

To all whom it may concern:

Be it known that I, BJon'ouLo Nons'roo, a citizen of the United States,residing at Watford City, in the county of McKenzie and State of NorthDakota, have invented certain new and useful Improvements 1n .DirigibleHeadlights, of which the following is a. specification, reference beinghad to the accom 'ianying drawings.

This invention relates to certain improvements in dirigible headlightsand has relation more particularly to a device of this general.character especially designed and adapted for use in connection withvehicles of a motor-driven type; and it is an object of the invention toprovide a device of this general character having novel and improvedmeans whereby the headlight will be caused to more in unison with and inthe same general (l'lreoiion asthc steering wheels.

It is also an object l the invention to pro vide a device of this moralcharacter hav ing novel and improve means \vherebythe same may besupported in applied position.

The invention consists in the details of construction and in thecombination and arrangement of the Several parts of my improvedheadlight whereby certain important advantages are attained and thedevice. is ren dered simpler, less expensive and otherwise moreconvenient and advantage iius for use. all as will be hereinafter more.fully set forth.

Thef'novel features of the invention will hereinafter he definitelyclaimed.

In order that my invention may be the better understood, I will nowproceed to describe the same with reference to the accompanyingdrawings, wherein-- Figure 1 is an elevational view of af'vehicleillustratin an embodiment of my invention applied t iereto;

Fig. 2 isa fragmentary View in top plan of the forward end portion ofthe vehicle with my invention as herein embodied applied thereto and'with certain of the parts indicated by dotted lines;

. Fig. 3 is a view partly in elevation and partly in section of adirigible headlight constructed in accordance herein disclosed;

'Fig. 4 is a View partly 1n sectionand with my invention as partly inelevation of the upper portion of said sleeve can be readily the deviceas disclosed in Fig. 3 and at substantially right angles to thedisclosure in Fig. 3;

Fig. 5 is a sectional view taken substantially on the line 55 of Fig. 4and Fig. 6 is a sectional View taken substantially on the line 6-6 ofFig. 3.

As disclosed. in the accompanying drawings, A denotes the front axle ofa motordriven vehicle and which is of a conventional type. Coaeting withthe axle A are the clamping blocks 1 through which is reniovablydisposed the. shank 2. the outer end portion of said shank beingprovided with the perforate head 3 while the opposite end portion of theshank has removably disposed therethrough a 1 in preferably c0 actingwith the washer ."i surrounding said shank whereby it will he mreeivedthat the blocks 1 will be efl'ectively clamped upon the axle A yetcapable of being readily and conveniently removed when the requirementsof practice may so necessitate.

(i denotes a vertically disposed rod loosely directed. through theperforate head 3 and capable. of axial rotation, and the lower extremityof said rod (3 is provided with the extension 7 preferably at rightangles to the rod (a The outer end portion of the extension 7 isreduced. as indicated at 8. and seated within the horizontally disposedsleeve 9 provided with the depending shank 1O loosely directed throughthe head or block 11. The shank 10 has disposed therethrough a.removable pin 12 whereby it will he perceived that. the sleeve 9 iseffectively held against accidental displacement although removed whenrequi red.

The block or head 11 is adapted to be clamped to the steering rod ll. ofany ordinary or preferred type, said clamping means, as indicated at14., being of any preferred clnlracter.

Surrounding the rod 6 is the annular member" or sleeve 15 which is heldagainst movement longitudinally of the rod 6 through the. medium of theset or clamping screw 16. The annular member or sleeve 15 is adapted torest upon the upper face of the perforate head 3 whereby a downwardmovement of the rod is limited. It will also be 30 her 2-3 may bereadily bore 18 being of substantially the same cross sectionalconfiguration as the reduced portion 17 so th it the sleeve 19 will becaused torotate in unison with the rod 6." The sleeve 19 is freelypositioned .within the upstandin barrel 20, the lower end portion ofwhici is provided with the flange 21. to provide means whereby the samemay be secured to a suitable support such as a mud guard or fender G ofn motor-driven vehicle 20 and as indicated by dated liner; .n Fig. 2.

The upper end nor on oi the sleeve 19 is enlarged, as innozat l a; toaiiord a head resting upon lhe h per eJd oi the barrel 20 whereby llh:slev 19 rmaintained as in applied position Sui-rewriting the head 22 isthe annular men er 51? held in applied position upon -ai-Z b nd 22through the medium of llio clamp ng screw 24. As is believed to be scllcvhiem the annular memadjusted either longitudinally or axially of thehead 22, as the occasion may require. 4

The annular member 215 is provided with the arms 25 adapted to ali'ord asupport for the lamp or headlight l., said lamp or headlight L beingindicated by dotted lines in he periphery of the sleeve 19 at apredetermined point internu-diate its length is provided with theannular recess or groove 26 which is adapted to receive the pin 27disposed through the sleeve 19 and partially intersecting the borethereof. By this arrangement it will be at once self-evident that thesleeve 19 is effectively held a ainst longitudinal movement indepemlenty of the barrel 20.

As the steering rod R forms no particular part of my present. inventionand as the arrangement and operation thereof is believed to be obvious,a detail description and illus tratlon of sald rod and as particularlyre lates to its operation has been omitted. This is also true of theaxle A.

Surrounding the barrel 2 at a llltkll'ltfmined point mtcrincdiate ilslength is lhe split clamp 31 provided with the forwardly directed shank28 disposed through the tr ss rod 29 interposed between the guards or anfenders G, and coacting with the outer end ortion oi the shank 28 is thenut 30 wherey' it will be at once self-cvident that the truss 29 servesas an additional means to support the barrel 20 and to hold the sameagainst vibration. It is also to be noted that the split of the clamp3.1 is extended lon itudinally of the shank 28. i

l rom the foregoing description, it is thought to be obvious that aheadlight constructed in accordance with my invention is of an extremelysimple and com aratively inexpensive nature and is particu arly welladapted for use by reason of the convenience and facility with which itmay be asseinbled, and it will also be obvious that my invention issusceptible of some change and modification wit out material departurefrom the principles and spirit thereof and for this reason I do not wishto be understood as limiting myself to the recise arrangement andformation of to several parts herein shown in carrying out my inventionin practice, except as hereinafter claimed.

I claim:

1. In combination with an axle of a vehicle, clamping members eo-actingwith said axle, a headed shank disposed throu h said clamping members,means carried y the shank and co acting with the clamping members formaintaining said members in operative enga ement with the axle, a lampsupporting ro rotatably supported by the headed shank, and means forrotating said ro 2. A device of vthe character described comprising arodmounted for rotary movement, means for rotating said rod, a barrelsupported independently of the rod, a sleeve rotatably mounted withinthe barrel and provided with a bore angular in cross sec tion, an endportion of the rod being snugly insertible within the bore of the sleevebut capable of longitudinal movement independently of the sleeve, lampengaging means carried by the sleeve, and co-acting means carried by thebarrel and the sleeve for holding said barrel and sleeve againstrelative longitudinal movement.

3. A device of the character described comprising a rod mounted forrotary movement, means for rotatingsaid rod, a barrel supportedindependently of the rod, a sleeve rotatably mounted within the barreland provided with a bore angular in cross section, an end portion of therod being snugly inscrlible within the bore of the sleeve but capable oflongitudinal movement indepnndcntly of the sleeve, and lamp engagingnu-ans carried by the sleeve.

4. A device of the character described comprising a rod mounted forrotary movenn'nt, means for rotating said rod, a barrel supported indc'icndcntly of the rod, a sleeve rotatably mounted within the barrel andprovided with a bore angular in cross section,-an end portion of the rodbeing snugly inscrtible within the bore of the sleeve but capable oflongitudinal movement independently of the sleeve, lamp en gaging meanscarried by the sleeve, and means engageable with the barrel intm'me(ll-ale the length thereof to lllord an additional suppoft for thebarrel and to hold the same against vibration.
